- Salinity Gravimeter: Keep your hands clean while preventing water contamination in fish ponds. This tool helps maintain optimal water quality for your aquatic life. - Aquarium Gravimeter: Features a user-friendly display for easy reading. With a precision of ±0.001 units of specific gravity, it delivers accurate readings even at temperatures as low as -28 degrees Celsius. - Hydrometer: Designed with a 15-centimeter (6-inch) length from the bottom of the water, this design minimizes errors caused by oil films on the water surface, ensuring reliable measurements. - Salt Water Gravimeter: Automatically detects the proportion of the water sample. It provides simultaneous readings of water proportion, salinity, and conductivity, making it a comprehensive solution for monitoring seawater quality. Applications: - Ideal for fishpond owners to regularly monitor salinity levels, ensuring a healthy environment for fish. - Perfect for aquarium enthusiasts looking to maintain specific gravity within optimal ranges for different aquatic species. - Useful for marine biologists and researchers conducting field studies on water quality in various aquatic ecosystems.
